Yama,not an expert,but have done running boar at Bisley a few times,basically you need to aim at a point in front of the target area that gives you the best score(from 1 to 10) you can buy a specialised scope that has 2 vertical lines on the ret that makes it easier to track the target point,never used one,I just tracked his nose to hit the target,great fun by the way
